    You can execute Python scripts directly from VBA in Excel, Word, or Access by invoking the Python interpreter through the Windows Shell. This is useful when you want to integrate Python’s data processing or automation capabilities into your VBA workflows.

    Using WScript.Shell for Execution

    Step 1 – Prepare Your Python Script

    • Ensure your .py file runs correctly from the command line before integrating with VBA.

    • Use absolute paths for files inside your Python script to avoid path issues.

    Step 2 – Add VBA Macro

    Sub RunPythonScript()
    Dim objShell As Object
    Dim PythonExe As String, PythonScript As String

    ' Create shell object
    Set objShell = VBA.CreateObject("Wscript.Shell")

    ' Paths to Python and script (triple quotes handle spaces in paths)
    PythonExe = """C:\Users\me\AppData\Local\Programs\Python\Python39\python.exe"" "
    PythonScript = """C:\Users\me\Documents\myscript.py"""

    ' Run script and wait until it finishes
    objShell.Run PythonExe & PythonScript, 1, True

    MsgBox "Python script executed!"
    End Sub
    Copied!
